High-yield and high-quality carding

One is to keep the carding machine spacing accurate. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine.

Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process. The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process).

To be precise and accurate, the basic work must be done well. 1. Before the new packing, the cylinder impact cylinder should be corrected to make it dynamically balanced, the amplitude should be controlled within 0.05 mm, and the cylinder body should be ground to meet the technical requirements of flatness and roundness, so as to maintain the cylinder and surrounding parts. distance. The old card clothing is leveled by regular grinding work.

2. When wrapping the card clothing, strictly manage and control the difference in tooth height, and try not to grind the needle after wrapping, so as to avoid the continuous increase of the area of ​​​​the tip of the needle tip and reduce the sharpness of the needle tip. Four fast and one male should not only keep the distance between the needle surfaces accurate, but also require sharp needle teeth and light measures. Reasonable selection of carding elements for carding machine The choice of the specifications of carding elements (card clothing, buttons, strips) is a key factor that determines the quality of enterprise products and services.

(1) Selection of elastic card clothing 1. Processing short fibers, spinning high yarn elbows, and selecting a smaller number of card clothing, on the contrary, spinning slender fibers and spinning low yarns, using a higher number of card clothing. figure 2. The number of doffer clothing should generally be 10-20 higher than the number of cylindrical clothing, the number of dogs, and the doffer transfer rate.

(B) The choice of the card flat clothing according to the choice of raw material jersey jilin treatment and the type of clothing species. Jinlin is soft wire, high-density needle selection electrode cover clothing when spinning output is moderate and low resolution. When the cylinder is metal wire, such as polyester spun yarn gauge thick needle cover is selected, small and dense straight needle clothing.

The cylinder is a metal wire, a number of textile cotton yarns, when the output medium, the cover should use a very fine needle, the needle is high-density correction, curved flat garments. Flat card clothing, traditional hard, soft soft, dense and dense hard principle. For flexible card clothing, the number of needles in the cloth sleeve should be higher than that of the former pear skin, and the flatness and smoothness of the new needle point cloth should be higher for the main purpose, and the old flat side can be combined.

(2) The first criterion is that the enterprise maintains the accurate spacing of each part of the carding machine. To achieve a tight and accurate distance, we must do a good job of basic research. 1. Before the new packing, the cylinder impact cylinder should be corrected to make it dynamically balanced, the amplitude should be controlled within 0.05 mm, and the cylinder body should be ground to meet the technical requirements of flatness and roundness, so as to maintain the cylinder and surrounding parts. distance.

The old card clothing is leveled by regular grinding work. 2. When wrapping the card clothing, strictly manage and control the difference in tooth height, and try not to grind the needle after wrapping, so as to avoid the continuous increase of the area of ​​​​the tip of the needle tip and reduce the sharpness of the needle tip. Four fast and one male should not only keep the distance between the needle surfaces accurate, but also require sharp needle teeth and light measures.
